Tao,
Check locally for someone who repairs fork lifts or hydraulic lifts. They
should have the parts and expertise you need to make the repair. It sounds
like an air-over-hydraulic lift with worn seals.

Subject: [mems-talk] Our evaporator has a problem with the hoist.
Hi,
We have a CPA 6" diffusion pump evaporator. Now it has some problem
with the hoist when lifting up. It's stuck there. Normally, it will
be automatically up when the air pressure is 75 psi. However, it
doesn't work until the pressure goes up to 90 psi. We know it operates
under the oil and air pressure. Anyone if knows how to solve this
problem,or how much oil it requires to operate,or any troubleshooting
manual, please email to me. Your help is greatly appreciated. Thanks.
